Answer:
4
Explanation:
To Obtian the possible dimensions of the array :
List out the factirs of 54 and use a pair of each in multiplication to obtain 54 ; Theb number of multiplication pairs obtained is the number of possible dimensions of the array :
Factors of 54 : 1, 2, 3, 6, 9, 18, 27, 54
Muliplication pairs :
(6 * 9) = 54
(18 * 3) = 54
(27 * 2) = 54
(54 * 1) = 54
Hence, there are 4 possible dimensions of the array
